Continuity mistake: Schofield's son's eyes change position at the hospital when Linc talks to him. They go from looking outward to looking down in the space of one shot. That shot is a wide to a closer shot of the same scene with no time difference.

Continuity mistake: When Lincoln stands in the back of the pickup truck behind the machine gun, you can see from the shot from behind that there is a ammo box next to the gun. When the shot changes to the front, no ammo box is there. Also when he shoots the gun, there is no ammo placed.
